Grotrian For more than 150 years, German manufacturer Grotrian-Steinweg has been known for its dedication to pushing the forefront of piano innovation – and not only in terms of their own instruments, but for the craft as a whole.
The Grotrian-Steinweg piano factory was built by Heinrich Engelhard Steinweg (later known as Henry Steinway after his emigration to the US where he founded Steinway & Sons) and Friedrich Grotrian. The Grotrian company is celebrated in the industry for fundamentally changing how pianos were constructed. From developing the first precise scale design, to the homogenous soundboard, to the star-shaped back construction, to the legendary upright model 120, Grotrian is regarded as a leading pioneer in the field of piano design and construction. Perhaps their most exciting innovation was the Grotrian Duo, which bridges two grand pianos under a single lid for dual or solo performance.
